CULTIIVATOR.

Specification of Letters Patent. Application filed December 23, 1905.Serial No. 293,104..

Patented March 20, 1906.

To all whom it may concern;

Be itknown that I, FLori) LESLIE A DER- soN, a citizen ofthe UnitedStates, residing at Auburn, in the county of Nemaha and State ofNebraska, have invented new and useful Improvements in Cultivators, ofwhich the following is a specification.

This invention relates to cultivators, and

more particularly to that class known as tongueless cultivators,in whichtwo shovelbeams are connected at their front ends to an arched framemounted on wheels, with the draft. devices connected in such a mannerthat the draft is applied directly to the beams.

The invention has for its object improved means for operating the shoeor runner which is'employed'for supporting the cultivator in an uprightposition, so that said shoe or runner can be readily raised or loweredwithout the trouble and labor of loosening and tightening any nuts. g

In the accompanying drawings, Figure 1 is an elevation of a portion of acultivator, show+ ing the application of the invention,- the shoe plate'The parts thus far described are to be being shown in elevated position.Fig. 2 is a similar view showing the shoe lowered into contact with theground. Fig. 3 is a vertical section on the line 3' 3 of Fig. 2. Fig. 4is a denotes the arched frame of the cultivator, to

which the shovel-beams (not shown) are coupled. The draft-plate 6 ispivotally connected atits rear end to the frame 5 by a pin 7, whichextends through ears 8 on said plate and ears 9 on the frame. The wheel10 is mounted on a stub-axle carried by the draftfound in an ordinarytongueless'cultivator and nothing is claimedwith respect thereto, and afurther description is therefore thought unnecessary.

The shoe or runner and is connected at its front end to the draftshoe,as at 18.

for holding the mav chine in upright .position is indicated at 11 clinedslot 13 in said plate. The bolt has a reduced end 14, which is threadedto receive plate 6 by-abolt 12, which works in an ina fastening-nut 15.The shoe is placed on the reduced end of the bolt and is clamped betweenthe nut 15 and the shoulder formed by said reduced end. The rear end 16of the shoe, which engages the ground, is flattened, as usual.

At 17 is indicated a-fiat spring, which is riveted or otherwise securedto one side of the The purpose of this spring is to hold the shoe out ofoperative position, it being slipped over the coupling-pin 7 when theshoe is elevated, as shown inFig. 1. part of the spring which fits overthe couping-pin is shaped to form a groove or corrugation 19 to receivethe pin. When it is de' .sired to lower the shoe into operative osition,the spring is released from the coup ingpin, which frees the shoe andpermits it to be owered to the position shown in Fig. 2. The free end ofthe spring is curved outwardly, as at 20, so that when the shoe ispushed forwardly to elevate it the spring will automaticallyengage thecoupling-pin. The part 20 also affords convenient means for grasping thespring when the shoe is to be released if the s ring is too stiff toslip readily off the coup ing-pin.

- The fastening device herein described will lessen the labor and timenecessary in shift- That ing the shoe from the position in which it isplaced when the cultivator is working to a position for traveling on theroad or in moving from onefield to another.

There are no nuts to tighten or loosen, and the use of a wrench istherefore dispensed with.

The combination with the slotted draftlate of a tongueless cultivator,and the coupling-pin thereof, of a shoe slidably mounted at its frontend in the slot of the draft-plate, and a s ring-clasp carried by theshoe and engagea le with the coupling-pin.

In testimony whereof I have signed my name to this specification inthepresence of two subscribing witnesses. I

FLOYD LESLIE ANDERSON.
